Used Sprint Moto X No SIM card included, how hard is it to get one?

I am looking at a Sprint Moto X that is used and has a clean ESN. They don't include a SIM card. I was wondering how hard is that to actually get from Sprint and is there a cost? If it's too much then it's not worth it may be better for me to buy new.

Second, Sprint Moto Xs are SIM-locked, so they will not work with Verizon, Tmobile, etc. They can be unlocked for International SIMs only by calling Sprint and asking (I believe this requires that the phone be activated on Sprint for at least 30 days, and the account be in good standing).

First this belongs in Q and A section. Second, Sprint doesnt even use Sim cards, I have Sprint Moto X and the only reason there is a sim card in there is for the phone to stop telling you "NO SIM" its basically a place holder. and the only way they will give you one if activate or buy a phone from them
